CHAIN. i

Application filed' September 16, 1907. Serial No. 392,988.-

resident of Weehawken, in the county ofA B IHudson and State of New Jerse have invented certainV new and' usefuj Improvements in Chains, of which the following is a specification.

In theK operation of dredging buckets of the types commonly known as clam-shell and orange peel, it is customary to employ, among other mechanism, a chain for the o ening and closing mechanism, such chain eing wrapped about a wheel or drum upon. a shaft connecting the bucket sections. -Heretofore, at times .diiiicult has been experienced in the operation O these buckets ecause the chains in wra ping or coiling one section upon the other, ad a tendency 'to entangle.

Among other purposes, therefore, I aim to devise a chain formed of a plurality of sections so connected and arran ed one section relative to the other, that in t e wrapping or windingl of the chainaround a shaft or drum the sections will not overlap but will lie one between the other. to be limited to the particular use described for my chain as it is my purpose, irst to provide a chain useful for many purposes and one which will embody the desired features of sim licity and durability.-

In t e accompanying drawings like characsters, of reference indicate like parts in all the views. Y

Figure 1 is a View in side elevation of a chain embodying my improvements; Fig 2 is a view in iront elevation; Fig. 3 is a lan view of one of 'the lower terminal links, w ich link is desi ned to be connected by a pin or the like witiii a bucket or other article; Fig. 4 is a plan view of one of the intermediate links going to make u the chain; Fig. 5 isa plan view of a single ink; Fig. 6 is a plan view of 4.5 the hanger link b y means of which the chain may be suspended from any suitable point; Figs. 7 and 8 illustrate modifications of my invention.

Referring now to the accompanying drawings in detail and especially to Figs. 1 and 2, A indicates one section of the chain, which mav be considered as a single section, and B indicates a second section of the chain which may benonsidered as a double or duplex section, the two members 5, 5 of tins double Specification of Lett-ers Patent;

duplex section being suspended from the pin 7 passing through the sleeve bar 8 carried by one end of the section A,fsaid sleeve acting as a'spacer for thetwo members, 5, 5 of the section B. This sleeve bar spaces the two sec-A tions 5, 5 aparta suitable distance so that when the chain is coiled or wrapped the section A may occupy the space between the section 5, 5, thereby obviating the overlapping of the wraps of the chain. One of the sections, for instance, the single -section A, is provided with asuitable suspender or hanger 9 provided with an opening 10' for the passage of the suspending pin.v The chain sections A and B are formed of a lur-ality of individual links 11 and 12, the ink 12, which is the center link, lying between the two side links 11, and is connected therewith by a pintle 13 in the well rknown manner. The numeral 14 indicates a ter- 75 minal link having an opening 15, this link 14 being designed to be connected to a bucket or the like.

In Fig. 7 I have shown a .modiiied form of chain, in this case the section A is connected, in the manner heretofore described, with twov members of the section B, each ofl these members in turn carrying a sleeve bar 8. through which passes the pin 7? and from which in is suspended in turn two chain sec- 85 tions In Fig. 8 I have shown a further modiiication; in this case three 'chain members D', D', D, are suspended from the pin 7b. l

In all the constructions shown I embody a chain, which, as heretofore described, may

4 be coiled or wrapped ina manner to avoid the overlapping of the chain members when coiled about a drum or'shait.

What I claim is:

1. A chain formed of a plurality of connected sections, one of said sections being locked to an adjacent connected section so that it lies between the members forming the adjacent section when the chain is coiled or wrapped.

2. A chain formed of a plurality of sections, a sleeve bar carried by one of said sections, a in assing through said sleeve bar and a p ura ity of chain members forming 106 the next or ad'acent section', conne fiatoV aid pin and heid spaced apart by't eve" ar.
